CVE intelligence and bounded remediation

CVE-2019-15911 — An issue was discovered on ASUS HG100, MW100, WS-101, TS-101, AS-101, MS-101, DL-101 devices using ZigBee PRO

Critical CVSS 9.8

An issue was discovered on ASUS HG100, MW100, WS-101, TS-101, AS-101, MS-101, DL-101 devices using ZigBee PRO. Because of insecure key transport in ZigBee communication, attackers can obtain sensitive information, cause the multiple denial of service attacks, take over smart home devices, and tamper with messages.

Matched remediation archetype

Cryptography, certificate, signature, and channel validation

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Inventory affected algorithms, key uses, trust stores, certificate validation settings, random sources, and plaintext channels across clients and services.
  • Determine which secrets, identities, signatures, or data protections depend on the affected primitive or validation path.
  • Check debug, compatibility, fallback, and hostname or audience override settings in build and runtime configuration.

Remediate safely

  • Use a maintained platform cryptographic API with approved algorithms, modes, parameters, randomness, and full peer identity validation.
  • Remove insecure fallback and validation bypasses; separate keys by purpose and load them from managed secret storage.
  • Plan rotation or reissuance for affected keys, certificates, tokens, hashes, or ciphertext and document compatibility sequencing.
